SPECIFICATION forming part of Letters Patent No. 390,159, datedSeptember 25, 1888.

Application filed April 3, 1886. Serial No.197,707. (No model.)

To all whom it may concern.-

Be it known that I, LEVI M. DEVORE, a resident of Freeport, in thecounty of Stephenson and State of Illinois, have invented certain newand useful Improvements in Cork-Extractors; and I do hereby declare thefollowing to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which it pertains tomake and use the same.

The object of my invention is to provide more reliable means forremoving the cork from the corkscrew after it is drawn from the bottle,it having been found that owing to differences in the corks themselvesall the extractors with which I am acquainted occasionally fail, ifintended to automatically split and discharge the cork by causing it topass a knife.

My device dispenses with a knife or cutter and bursts the cork by simpleoutward pressure from the interior of the cork.

In the accompanying drawings, to which reference is bad in thisspecification, Figure 1 is an elevation of a cork-extractor embodyingone form of my invention; Fig. 2, asection on the line as y, Fig. 1;Fig. 3, a section on the line :r 3 Fig. 1.

Animportantfeature of my invention is, al lowing the cork to rotate iffriction upon the corkscrew exceeds that of the bottle and of thebursting device combined, thereby avoiding screw is actuated by a crank,D E F, and has upon its upper end a sharp wire-removing hook, G.From'the bearing Oalug, whose inner face closely fits the cylinder ofthe corkscrew-spiral, extends downward nearly to the bottle-neck whenthe latter is in position to be arrested by the stop K, as shown. Thecon tour of this lug is shown in Figs. 1, 2, and 3. The stop K isprovided with an aperture to allow the ordinary bottle-neck to projectentirely through it or nearly to the point of the lug 0, while in theordinary form the end of the neck meets the stop below the upper surfacethereof.

The portion of the spiral alongside the lug 0, Fig. 1, is turned down orotherwise made of less diameter than the partimmediatelybelow the lug,in order that the point of the lug being within the elements of theouter surface of the lower portion may more readily enter the risingcork.

A most important advantage of my device is that the cork is at alltimesengaged throughout its entire length by the corkscrew, and isconsequently carried upward thereby even when its lower end has passedthe point of the rupturing-1ug,and thus is completely ruptured from endto end. The importance of this construction is more evident when it isconsidered that were the cork engaged only by that portion of the screwbelow the rupturing device the engaged portion must at last (in eachcork extracted) become very short, and that consequently the continuedrotation of the screw, instead of advancing the cork over the rupturingdevice, bores or grinds out its central portion and allows the fragmentsto fall into the open mouth of the bottle.

It is convenient, but not essential, to form the lug integrally with thebearing, for if both lug and bearing be cut on the line as y the deviceis still operative.

I am aware that others have combined with a corkscrew adapted to extractcorks by its own rotation without longitudinal movement a fixed sleeveinclosing the corkscrew-stein, and having a cork-rupturing blade whosee11- tire working-edge slopes upward and outward from said sleeve,whereby the rotation of the cork with the corkscrew is hindered, whilethe cork is ruptured by radial outward force alone; and I do not claimsuch combination as my invention.

Having now fully set forth my invention, I do not claim as new all theparts shown, but only such novelty as is set forth in the claims whichfollow:

1. In a corkextractor, the combination,

with a longitudinally-fixed,rotary, spiral corkscrew supported by afixed standard, of a cork-rupturing wedge rigidly connected with saidstandard lying alongside the upper part of the spiral portion of saidcorkscrew, and adapted to enter the rising cork and by radial force fromthe inside outward rupture it upon one side,whi1e the opposite side isstill engaged throughout its entire length by the spiral portion of thecorkscrew, whereby the automatic rupturing of the lower as well as theupper portion of the cork is rendered more certain.

2. In a cork-extractor having a longitudinally-fixed corkscrew revolublymounted in a stationary bearing, and a stop limiting the movement of thebottle, the combination, with a corkscrew having the diameter of theupper 1
